Lets's calculate GCF of 109,106
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 109
:1,109
Now, list down the factors of 106
:1,2,53,106
Greatest Common Factor
We found the factors 109,106 . The biggest common factor number is the GCF number.
So the greatest common factor 109,106 is 1.
Lets's calculate LCM of 42,689
Given numbers has no common factors except 1. So, there LCM is their product i.e 28938
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28938
Therefore, the GCF of Fractions 109/42,106/689 is 1/28938
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 42,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(42,689) x common factors =1 x 1 = 1
LCM(42,689) = ( 42 × 689 ) / 1
LCM(42,689) = 28938 / 1
LCM(42,689) = 28938
